Slow Movies

Lately all the movies I've seen have been a drag. They've been good but I feel that the same message and intensity could have been accomplished in less than 2 1/2 hours. Whatever happened to the 1 1/2 hour movies? In today's world, no-one has the time to spare 2-3 hours to sit and just stare at a screen. For example, Transformers 2, it was way too long. 1 1/2 hours of an action movie is good enough; they could have cut down some machine-fighting scenes.
